Serial No. 774,7e1.

2 '0 all whom it may concern:

Be it known that I, ARTHUR W. SMITH, a

citizen of the United,,States, and resident of tion the frame of the machine is of the usual construction, such as that employed in the Nos. 10 or 11 Remington machines and in and useful Improvements in Type-VVriting I Machines, of which the following is a specification.

My invention relates to typewriting and like machines, and the object of the invention is to provide simple and efficient automatically operating means for arresting the carriage at different points at successive return movements of the carriage, in order to facilitate writing addresses, for example, on work sheets or cards.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangement of parts and combinations of devices set forth in'the following description and particularly pointed out in the appended claims.

In the accompanying drawings in wh ch like reference characters designate like parts in the various views, Figure 1 is a fragmentary plan view of one form of typewriting machine embodying my invention. Fig. 2 is a detail fragmentary front elevation of the means for arresting the carriage in its return movement and some of the associated parts. Fig. 3 is a detail perspective yiew of a portion of the carriage arrestingmeans. Figs. 4, 5 and 6 are detail front elevations of the same with parts in section and parts broken away, these views illustrating the parts disposed as they appear in different conditions of use.

The present case is a division of my application Sr. No. 752,848, filed March 8th, 1913.

While 1 have shown my invention embodied, in the present instance, in a typewriting machine having needle faced types, and one intended primarily for writing or preparing stencil cards or sheets, t should be understood that theunvention 1S applicable to ty writing and like mach nes generally, and t at the novel devices of the invention may be regarded in the nature of an attachment which may be readily affixed to various styles of typewriting ma= chi s W thout modifying, or materially J lmodifying, the structural features of those machines as they now exist.

In the present embodiment of the invenwhich a top plate 1 supports fixed front and rear guide rails 2 and 3 respectively. The carriage comprises front and rear guide rails or cross-bars 4 and 5 respectively and end bars 6. Anti-friction balls or rollers are re ceived between the guide rails Qand 4, and 3 and 5 and support the carriage for movement over the top plate of the machine.

In the present instance the carriage supports a hopper or chute which receives a series of work sheets or cards 8 which are automatically fed to work sheet feeding means, not shown. Such work sheet feeding means are controlled by a handle 9 that is effective to return the carriage to the right to begin a new line of writing and to simultaneously actuate a link 10 by which the work sheet feeding means are controlled and by which the cards or work sheets are successively fed to a platen 11 carried by the carriage.

The carriage is propelled from right to left, or in the direction of its feed, by a spring drum 12 to which one end of a band 13 is connected, the other end of the band being connected to a bracket 14: secured to the carriage by screws 15.

The carriage has a step by step letter s ace movement from right to left under control of the usual cscapement mechanism (not shown) and is limited in such movement by a stop 16 secured to the top plate by a screw 1.7. In the return movement of the carriage to the right it is arrested by the novel "devices of my invention at different points which are successively nearer the such as those employed in the Remington machines mentioned above.

The automatically operating means for yariably arresting the carriage in its return movement to begin a new line of writing, and by which the carriage is arrested at different positions which are progressively near the center of the machine at different return movements of the carriage, may be said to consist in the main of two members, one carried by the carriage and the other by the frame of the machine. Thus, the right hand supporting plate 20, which is connected to and travels with the carriage and may be regarded as a part thereof, has a bracket 21 secured thereto by screws 22. This bracket has an arm .23 which extends to the right and constitutes a support for a screw pivot 24. From an inspection of Figs. 1 and 2, it will be understood that the screw 24 passes freely through an opening in one side member or ear 25 of a sheet metal pawl or stop member, designated as a whole by the reference numeral 26. The opposite or parallel wall 27 of this pawl is tapped to receive the threaded end of thescrew 24. This screw also passes freely through an 7 opening in the projection 23 and receives a bearing therein by which the pawl is pivotally supported in place. The upper wall of the pawl which joins the two side members 25 and 27 is adapted to bear upon the upper surface of the projection 23 (see Fig. 2) to limit the downward movement of the pawl. This pawl or stop member terminates at the right hand end in an engaging nose 28.

A bracket plate 29 is secured by screws 30 to the top plate 1 of the machine at the right-hand side thereof. The bracket plate is formed with an upwardly extending plate-like rejection 31 provided with a series of teet i or stops 32, 33, 34. These stops are in the nature of ratchet teeth which are inclined upwardly from right to left and normally has a pathof movement which is indicated by the dotted line showing of said pawl in Fig. 4. The upper edge of the plate 31, at the inner end thereof, is beveled at 35 in order to lift the pawl against its own weight when the end of the-pawl is brought into cooperation with the bevel. Ordinarily an arrest of" the carriage would be effected by the pawl entering the space to the left of the tooth 32, which is the first tooth the pawl wouldencounter, in its movement to the I right with the carriage. However, I have provided controllin means for controlling the engagement of t e pawl with the different stops or teeth 32,33, 34. The controlling means in the present instance comprises a controlling member, device or shield 36 .which is in the nature ofa slide and has arectilinear movement, being supported by headed screws 37 which extend through a slot38 in the part 36 and are received at their threaded ends in tapped openings in the plate 31. This sliding plate is provided with three teeth or engaging portions 39, 40 and 41. Intermediate these engaging portions the upper edge of the controlling member is provided with dwells 42, 43, 44. ii contractile spring 45 is connected at one end to a pin or hook 46 which projects from the plate 31, the opposite end of the spring being connected to a pin 47 which projects from one side of the controlling member 36. The force of this spring is exerted to pull the controlling member to the left. A pawl 48 is pivoted by a headed screw 49 to the controlling member 36 and the engaging nose 50 of this pawl is adapted to co-act with ratchet teeth 51 formed on a block 52 which is fixed to the plate 31 by screws 53.

the spring is received in an opening 57 (see Fig. 4) formed in the hub of the pawl 48.

A leaf spring 58 is fixed to the bracket plate 29 by rivets 5-9. The left-hand end of the spring is bent forwardly and then upwardly and then rearwardly to form a fiat upper portion 60 which overlies the engaging nose 50 of the pawl 48 and forms a controlling device which cooperates therewith. Normally the portion 60 of the spring 58 is free from engagement with the nose 50 of the pawl but as the controlling member is moved to the right relatively to the stop carrying member 31, the engaging pprtion of the pawl would be brought into contact with the lower face of the part 60 of the spring, as shown in Fig. 5, thus elevating the free end of the spring. A movement of the controlling member from the position shown in Fig. 5 to that indicated in Fig. 6

is effective to cause the pawl 48 to lift the spring, and after the engaging portion of the pawl is withdrawn from beneath it to allow the part 60 to resume its normal position. At this time the engaging portion of the pawl in its return movement is adapted.

to contact with the upper side of the part 60 of the-spring, thereby maintaining the pawl out of engagement with the ratchet teeth 51 during the return movement of the controlling membcr 36, as indicated by dotted lines in Fig. 6.

It being understood that Fig. 3 shows the normal position of the parts, and that these parts are disposed as shown when the carriage is moved to the right to begin the first line of writing, it will be seen that in this movement of the carriage the pawl 26 will engage the dwells 42 and 43 on the controlling member, the pawl being thereby prevented from entering the notches of the first said member to the right with the stop or pawl 26 until the latter is arrested by engaging .the fixed stop 34. This'movement of the controllin member is efiective to carry the pawl 48 with it from the position shown in Fig. 3 to that represented in Fig. 4, which latter figure shows the disposition of theparts at the termination of the movement of the. carriage to the. right to begin the first line of writing. The pawl 48 engaging the first tooth 51 will retain the controlling device 36 in the position to which it has been shifted. The operator proceeds to write the first or name line and when this is completed the operator will again move the carriage to the right through an actuator of the handle 9, and at this time the controlling device 36 being in the position shown in Fi 4, the dwell 42 will prevent the pawl 26 from engaging the notch in advance of the first tooth 32', but will enable the' pawl to enter the notch in advance of the tooth 33. As the pawl enters this second notch it will engage the contact portion 40. on the controlling device, thus moving the controlling device from the position shown in Fig. 4 to that represented in Fig. 5, which last mentioned figure shows the disposition of the parts at the termination of the second return movement of the carriage to begin the second line of writing. I

A comparison of Figs. 4'and 5 will show that the carriage is arrested in its second return movement at an earlier period than in the return movement of the carriage for the first line of writing, thus properly arresting the carriage so as to offset the beginning of the second line, or the first line or the address. The parts are substantially in the position represented in Fig. 5 when the carriage is returned the second time. This will leave the controlling member 36 in the position shown in Fig. 5 where the dwell 42 no longer prevents the pawl 26 from entering the notch in advance of the tooth 32 on the'next return movement of the carriage. After the second line has been completed the carriage will be returned to the right and the pawl 26 will enter the notch in advance of the first tooth 32 and will engage the face Or contact portion 39 on the controlling member, forcing the latter to the right and carrying with it the pawl 48. The pawl 48 at this time moves up the incline 54 and releases itself from engagementwith the spring member 60, as shown in Fig. 6. This view represents theparts as they appear at the termination of thereturn movement of the carriage t begin the third line of writing. As hereinbefore explained, when the controlling portion 60 is lifted by the engaging nose of the pawl 48. in the movement of the latter to the position shown in full lines in Fig. 7e 6, the part as soon as released from control of the pawl 48 will be returned to normal position by its spring 58, so that the pawl 48 is prevented during the return movement of the controlling device 36 from 79 engaging with the ratchet teeth 51. As the carriage moves to the left in writing the. third line the controlling device 36, under the power of its spring 45, will move to the left-until the right-hand end of the slot 38 so in the controlling member engages the righthand screw 37. At about the termination of the return movement of the slide 36 the pawl will pass the left-hand end of the contact member 60 and will be forced to the lower- 35 most position shown in Fig. 3. It will be seen, therefore, that during the writing of the third line the controllin device 36 and the pawl 48 will return to t e normal position which they occupied prior to returning the carriage for beginning the first line of writing. It will be understood that the arrest of the carriage in its movement to the right, through the coeperation of the pawl 26 with the stop or-tooth 32, effects an arrest 96 of the carriage at an earlier point in its return movement than is effected by the cooperation of the pawl with the stop 33, so that a further oiisetting of the beginning of the third line of writing is effected. 100

It will be seen from the foregoing description that the controlling member 36 is intermittently actuated by the movement of the carriage to the right to control the engagement of the pawl with the stops or teeth 32, 33, 34, and that the carriage is arrested at points progressively nearer. the left-hand side of the machine while arresting thecarriage preparatory to writing the three lines to be inscribed on the stencil plate. \Vhile I have shown three stops 32, 33 and 34, it should be understood that any suitable number of such stops maybe employed. appropriate modification of the controlling member 36 being made accordingly.

In the parent application, of which the present case is a division, there are various features, in the mechanism for effecting a feed of the cards, which have elements in common with the construction forming the subject-matter of the present divisional application, and there are claims included in the parent case which have been drawn to cover this common subject-matter or construction generically. Thus, each mecha- 126 nism includes a toothed device, a coiiperating pawl and automatically operating controlling means for determining with which tooth of the toothed device said pawl or coacting member shall coiiperate. Each 130 v trolling member is in the nature of a toothed device which is actuated by the same pawl that coacts with the other toothed member.

In each case the controlling member is in the nature of a shield which prevents the cooperating pawl from engaging certain teeth of a toothed member, and in each case the shield is automatically actuated to determine with which tooth of the toothed member the pawl shall engage. In each case the pawl cooperates with a toothed member which is in the nature of a rack.

The claims in the present divisional case are restricted to that form of the construction which is shown herein, and the parent case contains generic claims which cover or include this construction.
